Speaker Specifications

Series

This is the manufacturer product line of speakers.

Priced Per

Car Speakers are typically sold in pairs so you will receive 2 speakers for each speaker purchase on speakers marked "Priced Per Pair".
If a speaker is marked "Priced Per Each" then the speaker is sold individually and each purchase you make will result in 1 speaker. High-powered tweeters, midrange and full-range pro audio for car speakers are typically sold per each speaker.

Speaker Size

Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.

6" x 9"

Design

The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.

3-way

Tweeter Design

Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.

Tweeter Size

Refers to the size of the tweeter. Typically, smaller tweeters produces less output with higher frequency response.

Tweeter Composition

Materials such as polypropylene, silk, cloth, and paper are the most common, where as many more recent tweeters are now manufactured with composites such as Aluminum, Titanium, Mylar, and other materials.

PEI is an acronym for "Polyetherimide" which is an amorphous, amber transparent, high-performance thermoplastic.

Woofer Composition

Lightweight woofer cone materials are essential for efficient operation. Poly cones produce exceptional sound and are sturdy against various changes in temperature. Paper cones are very efficient, and when treated for moisture resistance, will perform at a high level. Poly refers to polypropylene, which is thermoplastic or fibers that are polymers of propylene. IMPP refers to injection molded polypropylene, a commonly used process and material in speakers.

Woofer Surround

A speakers surround is part of the suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.

Peak Power Handling

Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements. The Peak power handling specification is typically rated per speaker unless otherwise noted.

300 watts

RMS Power Handling

The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.

100 watts

Sensitivity

An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".

92 dB

Frequency Response

The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).

46 - 21000 Hz

Impedance (Per Voice Coil)

The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.

4 ohms

Shallow Mount Installation

This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.

Top-Mount Depth

The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.

3"

Cutout Dimensions

Refers to the dimensions of the hole, measured in inches, required to contain the speaker.

Cutout Dimensions

Refers to the dimensions of the hole, measured in inches or millimeters, required to contain the speaker.

6-1/8 x 8-7/8

Speaker Grilles

A grating or screen of metal or plastic bars or wires, mounted in front of a speaker as protection. If yes, the speakers will include matching speaker grilles. If no, there are no grilles included.

These speakers are currently my rear speakers of my 2003 Mitsubishi Eclipse.

I have them hooked up to an Alpine F-450 amp and they sound awesome. Perfect combination to the Infinity 6020CS or 6010CS components systems from Infinity. These speakers have always had the bass I need and now with my amp in, they are some peppy speakers.

When you look for speakers, you look at sound and bang for the buck. These speakers are by far the best speakers for only $85 at sonic. They sold at BestBuy for around $150. You tell me, which is the better deal? Definitely worth the money

I have bought a pair of these speakers to replace my old stock 6X9's. These speakers rock my world. I have them hooked up to my radio and they sound amazing. They handle bass extremley well. I have driven down the street and had people turn their heads to the bass of these speakers. The treble also sounds really well. These are definetly worth the money.

Amazing SOUND. These have great bass and sound. The Highs deliver through great from the tweeters. Major difference from my stock speakers on my 06 ACCORD. I hooked these up to an Infinity AMP and am pleased with the sound. Only prob I had with these is that they do not fit exactly in my rear deck without me doing custom work.

I have a pair of these Infinity's and they sound great. I have an Audiobahn Amp at 50 RMS pushing these speakers and they only distort at insane volumes. I've tested them on a 50 watt Pioneer deck and they still sound great. The bass is great, but they sound better with a High Pass Filter set at 50hz. The sound is clear and hits perfectly. When powered the speakers sound amazing, but they sound impressive even without an amp. If you're looking for an up-grade to your stock speakers, don't look anywhere else but these Infinity speakers, and of course, you never need to look anwywhere else but Sonic.
